If I try to compute in a polynomial ring with arbitrary expression
coefficients, I get undesirable expansion:
>>> from sympy import *
>>> x,y,z,t = symbols('x y z t')
>>> Poly((x+y)*z,t,domain=EX)
Poly(x*z + y*z, t, domain='EX')
I would like to preserve the (x+y)*z structure of the coefficient for
later code generation purposes. Is there a way to do this?
Thanks,
Geoffrey
